Once the Dems narrow to one person, the right will attack the out of them. Trump's "record jobs" and "Stock Market 10K points" and "ended wars in blah blah blah" will be touted. People will hear that. They'll hear Warren say stupid about beliefs and half a dozen other things she's said. Or they'll hear Biden's gaffes, his son will continue to be dragged into the spotlight, his touchy feely #metoo practice sessions will be made into a looping ad.
Likewise the left will play about Trump being investigated. They'll say he's corrupt show footage of him and other leaders to make the point he's not on the side of America, and they'll show lists of all those under him who are now in jail or have been ousted or quit.
The sum could very well be "is your family better today than it was 4 years ago?" If you're Christian, do you want to sign onto late term abortions? Do you want your guns taken from you? Do you want to pay more in taxes so the immigrants being given amnesty get to live for free?
These are how it will likely pan out, but then, unlike you, I don't know.
